CUTTING AND PUNCHING TOOL.

Specification of Letters Patent.

Patented June 26, 1906.

To all whom it may concern:

Be it known that I, ADELORE JOSEPH LE- VIS, a citizen of the UnitedStates, and a resi-' dent of Houghton, in the county of Houghton andState of Michigan, have invented a new and improved Cutting and PunchingTool, of which the following is a full, clear, and exact description.

The invention relates to the cutting and punching of sheets and bars;and its object is to provi e a new and improved cutting and punchingtool more especially designed for the use of tinners, plumbers, andother mechanics and arranged to permit of forming tongues and slots inthe ends of stovepipesections to allow convenient interlocking ofadjacent stovepipe-sections.

The invention consists of novel features and parts and combinations ofthe same, which will be more fully described hereinafter and thenpointed out in the claims.

A practical embodiment of the invention is represented in theaccompanying drawings, forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure 1 is a side elevation of the improvement as applied on aStovepipe-section for cutting a tongue and a slot-therein, a portion ofthe Stovepipe being shown and in section. Fig. 2 is a transverse sectionof the same on the line 2 2 of Fig. 1. Fig. 3 is a perspective view ofthe cutter. Fig. 4 is a longitudinal sectional elevation of a stovepipe,showing adjacent sections interlocked; and Fig. 5 is a plan view of theends of adjacent stovepi esections provided with a tongue and a s ot forinterlocking purposes.

The parallel members A and A of the tool are pivotally connected with apair of pivoted handles B and B, adapted to be taken hold of by theoperator to impart a parallel motion tothe members A and A on closing Onthe member Aare removably secured a cutter C and a punch D, and in thetop face of the member A is for ned a recess C, arranged directlyopposite the cutter C, and in the said member A is also formed anaperture D in register with the punch D.

The cutter C is triangular in cross-section, and its bottom is inclinedupwardly from the apex to the base, and the registering recess C issimilarly shaped-that is, is made triangflar-and its bottom is inclinedupwardly om the apex to the base, so as to fully regpipe-section F. Onthe member A is ad' justably secured a gage E by the use of a setscrew Eor other suitable means, so as to gage the distance the aperture F is tobe formed from one end of the section F of a stovepipe or other articleto be provided with a slot. It is understood that the StovepipesectionsF and F are provided at adjacent ends with a tongue F and slot Frespectively, to permit convenient interlocking of theStovepipe-sections by engaging the tongue F with the slot F, as plainlyshown in Fig. 4f By the arrangement described it will be seen that theend of a Stovepipe-section can be readily passed between the members Aand A, so that the'top of the member A restsagainst the inner face ofthe stovepipe-section, and consequently the member A forms an anvil.When the Stovepipesection F has been introduced or passed between themembers A and A until the edge of the Stovepipe-section F abuts againstthe punch D and the handles B and B are pressed toward each other, thenthe member A moves toward the member A, and in doing so the cutter Ccuts the material of the stove pipe-section F to roduce the triangulartongue F. When tlie other section F is inserted between the members A Auntil the outer edge of the section abuts against the gage E and thehandles B B are pressed,

then the punch D shears the material of the- Stovepipe-section, so as toform the slot F By reference to Figs. 4 and 5 it will be seen that thetongue F and the slot F are in lonslot F is of a width slightly inexcess of the thickness of the material and the length of the slot issomewhat in excess of the width of the tongue F at the base thereof.When the the two Stovepipe-sections F F are joined together, the tongueF can be readily engaged with the corresponding slots F so as tosecurely interlock the Stovepipe-sections,

'gitudinal alinement with each other, and the as will be readilyunderstood by reference to Fig. 4..

The tool is very simple and durable in construction, is not liable toget easily outof order, and, if desired, the cutter C and the punch Dmay be readily removed from the member A for grinding purposes or to bereplaced by new ones whenever it is desired to Having thus described myinvention, I claim as new and desire to secure by Letters Patent 1. Acutting and punching tool comprising a pair of members, and means formoving the members parallel toward and from each other, one of themembers carrying a cutter and apunch, the punch being arranged behindthe cutter, and of greater length, where by to form a gage for thecutter, and the other member having a recess and an aperture forcooperating with the cutter and the punch, respectively.

2. A cuttin and punching tool comprising a pair of members, and meansfor moving the members parallel toward and from each other, one of themembers carrying a cutter and a punch and the other member having arecess opposite the cutter and an aperture,

opposite the punch, the said cutter having a trian ular cross-sectionand a bottom inclined longitudinally and upwardly from the apex to thebase.

3. A cuttin and punching tool comprising a pair of mem ers, and meansfor moving the members parallel toward and from each other, one of themembers carrying a cutter and a punch and the other member having arecess opposite the cutter and an aperture opposite the punch, the saidcutter having a opposite the punch, the said cutter having a trian ularcross-section and a bottom inclined longitudinally and upwardly from theapex to the base, the said recess corresponding in shape to the saidcutter and the bottom of the recess being inclined upwardly from thebase to the apex.

5. A cuttin and punching tool,comprising a pair of mem ers, and meansfor moving the members parallel toward and from each other, a cuttingdevice and a punching'device arran ed in longitudinal alin'ement betweensai with, the rear device being arranged to act as a gage for the frontdevice.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

ADELORE JOSEPH LEVIS.
